Google Nest Mini (2nd Gen)

Quick verdict

The Nest Mini is the cheapest way to put Google Assistant and a Google Cast target in every room. Audio quality is modest but fine for voice responses and TTS announcements. It is fully cloud-dependent and offers no smart home hub radios, but as a voice endpoint and Cast speaker it is hard to beat for the price.

Standout: Ultra-compact and affordable Google Assistant speaker that doubles as a Google Cast target for Home Assistant TTS.
